STARCH-TABLE.

SPECIFICATION. forming part of Letters Patent No. 254,063, dated February 21, 1882,

Application filed December 6, i881. (No model.)

To all whom it may concern:

Be it known that I, MICHAEL J. STARK, of Buffalo,in the county of Erie and State of New York, have invented certain new and useful Improvements on Starch Tables; and I do hereby declare that the following description of my said invention, taken in connection with the accompanying sheet of drawings, forms a full, clear, and exact specification, which will enable others skilled in the art to which it ap- .pertains to make and use the same.

My prescntinvention has general reference to starch-tables; and it consists essentially in such novel combination of parts and 'details of construction as are hereinafter first fully set forth and described, and then pointed out in the claims. l

The object of my present invention is the production of astarch-table that shall be durable in construction, readily adjusted, and easily kept in proper repair. To attain this end I construct my starch-table as illustrated in the accompanying drawings, already referred to, in which- Figure 1 is a sectional elevation, and Fig. 2 a plan, of my improved starch-table. Fig. 3 is a sectional elevation on a larger scale. Figs. 4 and 5 are end views of the adjusting device, and Fig. 46 a sectional elevation of the same.

Like parts are designated by corresponding letters of reference in all the figures.

`In these drawings, the letter A represents a starch-table, such as are used in starch, glucose, and other factories. This table is composed of a bottom, B, side pieces, C C', and an end piece, D, all constructed in the usual manner. The upper surface of this bottom B, as well as the inner sides of the side pieces, 0 O', are provided with a metallic sheeting, E, whereby the gutter formed by the bottom and side pieces is rendered water-tight, and at the same time prevented from speedy decay.

As heretofore constructed, the metallic sheeting is placed into the gutter or tables to present a smooth and level surface to the liquid holding the starch in suspension, and thereby to cause the deposition of said starch upon the tables without also retaining the gluten and other foreign matter, which will take place to a greater or lesser extent when eddies and other undulations are found in the hottom of Vthe tables; but owing to the fact that sheet metal is never perfectly flat, but always more or less bulged, it is impossible to line these tables with -metal in such manner as to produce a perfectly level surface. To overcome this obj ection I place into the tables, upon the bottom sheeting, an auxiliary bottom, F, of preferably matched stuff, running the boards lon gitudinally,(by preferen ce,)as clearly shown in Fig. 2. This auxiliary bottom, after being placed into the tables and securely fastened therein in any suitable manner, I then proceed to paint, coat, or saturate with some suhstance or material that will render the same more or less water-proof, so as to perfectly fill the pores of the wood,and thereby to prevent moisture, particles of starch, Src., from entering the same. I prefer to use as a medium to accomplish this result paraftine, which is, if at all, but slightly affected by the alkaline solution flowing over the tables. It is, furthermore, perfectly inodorous and tasteless, and comparatively cheap. The effect of thus saturating or coating the auxiliary bottom is that the bers of the wood are perfectly united and bound together, that they are impervious to water, and therefore prevent particles of starch from lodging in the pores and afterward fermenting, and that if for some reason or another the auxiliary bottom should become uneven, even to the slightest degree only, it can in a very short time be brought to a perfectly level surface by planing, scraping, or other analogous operation.

Owing to the fact that the pores of the wooden auxiliary bottom are filled and the fibers bound together by the application of paraffine or analogous substances, the said bottom is not liable to splinter when theI starch is shoveled away from the tables, and thereby overcomes another great and serious objection to the wooden tables now in use. t

It being essential that the bottom of the tables form a perfect plane, it is obvious that the tables should be kept in such a condition. Owing to the fact thatin buildings where starch, &c.,`is manufactured the weight or load upon the several lioors is always varying and fluctuating, hecansc large tanks or vats are sometimes lled and at other times empty,it is necessary to provide the tables with means for IOO raising and lowering them. shouldbe so constructed asto he readily and I These means by means of which I can rotatesaid cam-disk around its pivot a. v i

It will now be readily observed that by re-v volving the camdislz in one or the other direction I' can increase 'or decreasethe space between the base and bearing orlcnrrying plates, and thereby reiseI and lower the table in every convenient manner. Itiwill befur-f ther observed that adjustment cnn be madein i 1a veryshortspace ottime, ,since n quartcrrevolution of said disk will cause a. difference i 20 vin the height of the tables of oneinch, (more 1 orless,:) according tothe throw of the cam-d isk.
